Percy didn't have enough time. They would all be gone and Earth would be destroyed. Percy couldn't let that happen. Percy ran and ran and saw a terrifying scene miles ahead. Percy ran and took the swipe that was meant to kill someone else. Their hero was gone. Perseus Jackson, their hero was gone forever.
A son of Sea shall rise
To defeat one who's rage
unleashes their wrath, but foretold
one who has been betrayed not once nor twice
but thrice shall save the world or doom the world to it's fate
